v0.15.0

This release features **4 weeks of work** from **6 contributors**. It brings service logs streaming, new service management commands, SSH CLI connection mode, interactive cluster connection selection, HTTP/3 support, and various improvements and bug fixes.

## ✨ Highlights

### Service logs streaming

PR: #196
The new `uc logs` command streams logs from service containers across all machines in the cluster. Logs are merged from all replicas with colored output, strict timestamp ordering, and service/container identification.

You can filter logs by machine using `-m/--machine`, follow mode with `-f`, and time ranges with `--since`/`--until`.

Running `uc logs` without arguments streams logs from all services defined in the local Compose file.

### New service commands

PRs: #165, #195. Thank you @jabr for the contribution! ❤️

- The `uc ps` command displays all running containers in the cluster with service name, machine, state, health status, IP address, and creation time. You can sort containers by service, machine, or health status using the `--sort` flag.

- New `uc start` and `uc stop` commands allows starting and stopping all containers of the specified services across cluster machines. The stop command supports `--signal` and `--timeout` options for graceful shutdown control.

### SSH CLI connection mode

PRs: #152, #173. Thank you @luislavena for the contribution! ❤️

A new `ssh+cli://` connection scheme allows using the system's `ssh` (OpenSSH) CLI client instead of the native Go implementation of the SSH protocol for connecting to cluster machines. This makes it possible to init machines in private networks via `ProxyJump`, use hardened SSH agents like 1Password or Yubikey, and use existing custom host configuration from your `~/.ssh/config`.

If `ssh <target>` works from your terminal, then `uc machine init/add ssh+cli://<target>` should also work.

We will make this connection mode the default after addressing the edge case of removing machines when using the `ssh+cli` scheme.

### Interactive connection selection

PR: #170. Thank you @jabr for the contribution! ❤️

The new `uc ctx connection` command provides an interactive selector for choosing the preferred cluster connection among multiple configured ones.

### HTTP/3 support

PR: #204. Thank you @z0rrn for the contribution! ❤️

Caddy (reverse proxy) now exposes UDP port 443 for HTTP/3 (QUIC) protocol support, enabling faster HTTPS connections for supported clients.

### New managed DNS domain

Free managed DNS subdomains now use the new shorter `xxxxxx.uncld.dev` domain instead of `xxxxxx.cluster.uncloud.run` to separate the main project domain ([uncloud.run](https://uncloud.run/)) from the user cluster's domains. See [tweet](https://x.com/psviderski/status/1999109801616523715) for more details. Existing subdomains will continue to work.

You can run `uc dns release && uc dns reserve` to release your old subdomain and reserve a new one under `uncld.dev`.

## Improvements

- `--context` flag is now a global option available on all commands (#174)
- Unix domain socket connector for local daemon connections (#186)
- Machine ID stored on connection entries in `~/.config/uncloud/config.yaml` for automatic cleanup when removing machines (#182)
- Services sorted by name in `uc ls` output
- `IP ADDRESS` column added to `uc ps` and `uc inspect` output
- `CREATED` column added to `uc ps` with fallback sorting by creation time
- Machine install.sh script supports `INSTALL_ONLY` mode to skip daemon setup (#194)
- `uc --help` output shows links to documentation and Discord
- Minor documentation updates and improvements

## Bug fixes

- Fixed volume driver options not being used when driver is not explicitly specified (#211)
- Fixed new Compose deployment with volumes and `--recreate` flag (#176)

## Upgrade to 0.15.0

### Uncloud CLI locally

To upgrade the Uncloud CLI (`uc`) locally:

```bash
# Homebrew (macOS, Linux)
brew upgrade uncloud

# Install script (macOS, Linux)
curl -fsS https://get.uncloud.run/install.sh | sh
```

### Machine daemon

To upgrade the Uncloud daemon on your machines, run the following commands on each machine:

```bash
# AMD64
curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.15.0/uncloudd_linux_amd64.tar.gz
# ARM64
# curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.15.0/uncloudd_linux_arm64.tar.gz
tar -xf uncloudd.tar.gz
sudo install uncloudd /usr/local/bin/uncloudd
rm uncloudd uncloudd.tar.gz
sudo systemctl restart uncloud
```
